To Cannon or the practice of Cannoning is associated with the specific and highly regarded skill of hitting or cannoning a ball, while running at full speed. The ball would preferably be moving at a rate of knots at the time, however in exceptional cases (Alex, free kick, Chelsea vs Liverpool) a static ball is allowed.

The Cannon is a underused art in most professional sport, however it is slowly being reintroduced by purists of the game, it is now most commonly found in hockey at it highest level. Hockey allows the ball to be hit in a constantly rising trajectory until it is stopped only by the net.

Cannon
When someone is dissed so bad to the point that to make them feel better is by humiliating them even more. This term is an NYC term to draw attention to the victim and in fact making the victim feel even worst than before. You must also yell the word cannon otherwise it won't be used in the correct sense.
